168.41

anivartikā gatistasya rudralokādasaṃśayam /
kṛmikīṭapataṅgānāṃ tatra tīrthe yudhiṣṭhira /
aṅkūreśvaranāmākhye mṛtānāṃ sugatirbhavet //

his state of reaching the world of Rudra is non-returning, without doubt. / For worms, insects, and moths that die at that pilgrimage place / named Aṅkūreśvara, O Yudhiṣṭhira, there is a good destination.
